Combines separate git repositories into a single monolithic git repository, prepending the source repo name to every commit message. It only includes master branches from each repository, but otherwise complete version history is maintained. Mainly just a convenient bash wrapper around git commands.
Run the script from inside an empty git repository, for example:
#Describe the source repositories, see below for file format
$EDITOR repo_data.txt
#make an empty repository
git init $repo_name
cd $repo_name
#Run the merge/join tool
~/path/to/git-join-repos ../repo_data.txt
#Add the monolithic remote, this is just an example, plug in your actual remote:
#Be sure to run this step *after* the join tool.
git remote add origin git@github.com:username/monolithic.git
#Push it when you're ready
git push origin masterwhere repo_data.txt is in the format:
repo1 git@github.com:username/repo1.git
newname git@github.com:username/repo2.git
repo3 /path/locally/repo3
each row is separated by a newline and the name and url are separated by a space character (tabs not supported!).
Your new top-level working directory will contain:
repo1
newname
repo3
Where each subfolder contains the HEAD master commit from the corresponding source repository. n.b. old commit ids are lost in this process - so don't count on being able to reference your new repository with old commit ids.
Each commit message will be retained, but prepended with the name of the source repository.
